METHOD OF EMBROIDEFIING.

SPECIFICATION forming part of Letters Patent No. 776,265, dated November 29, 1904.

T0 rtZZ whom it may concern.-

Be it known that 1, AUGUST SOHNAUDER, a subject of the Emperor of Germany, residing at 12 Li'itzow street, Plauen, Vogtland, Germany, have invented certain new and useful Improvements in Methods of Embroidering, of which the followingis a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

In the manufacture of embroideries it has been customary to produce the design for the embroidering upon the fabric with the aid of stencil-plates by using colors containing resin. This was obtained in two different Ways-first, by the so-called dust-printing process, where the dry resinous colors are brought upon the fabrics by means of rubbing the color-dust through the stencils and then by fastening the colors by steaming the fabrics or by sprinkling alcohol or other solvents over the designs, and, secondly, by the so-called wet-printing process, according to which the respective colors are mixed with melted paraffin or with rape-seed oil and then applied with the aid of a brush. The admixture of paraifin to the color was indispensable, as it rendered the latter consistent, not running out, and thus being fit for printing. Of these two well-known methods the former has the disadvantage of a larger consumption of dye material and of being injurious to the health of the workmen on account of the fine dust of the colors.

In embroidering the articles in question it could not be avoided that the workman, especially if he works at finer articles, frequently misses the design, so that upon examination of the ready-made pieces many had to be laid aside owing to the lines of print still visible on them, or the articles had to be once more subjected to bleaching, whereupon an additional finishing of the fabrics became necessary. The present invention is destined to remove these defects, and in order to obtain a fabric with a plain design with colors standing well and not permeating the colors are mixed with kaolin, china-clay, hydrate of alumina, baryta, green earth, or similar substances capable of absorbing oils and, by preference, only such dyes or dye compounds are applied for dyeing which can be quickly and permanently decolored by a chemical treatment easily appliable and in no way damageable to the texture. Such compounds are, for

instance, iodic starch, chromic starch, the alkadesign in embroideringare touched with a- V solvent appropriate to permanently removing the color without damaging the texture.

For removing the blue design obtained by iodin, for instance, solvents of sulfid of sodium, sodium bisulfid, potassium suliid, or similar compounds of oxidizing properties can be applied, converting the iodin contained in the iodin starch into a combination which no more colors the starch.

For removing the yellow printing color a solvent of citricpyrotartaric or oxalic acid is used, whereby uncolored iron salts are formed.

The invention proves in so far of great advantage, as there will be no more inferior articles among the ready-made goods and inasmuch as the finished specimens require neither an additional bleaching nor a finishing impairing the quality; also any loss of time is thus avoided.

Having thus described my invention, what I claim is The method of embroidering, consisting in first stamping the design with an easily-eradicable ink, then making the embroidery on said pattern and afterward eradicating those portions of the design which are still visible because not covered by the embroidery by means of an ink-eradicator appropriate to take out the particular ink used to make the design.

' In witness whereof I have hereunto set my hand in presence of two witnesses.
